SLIDING-DOOR GUIDE.

SPECIFICATION forming part of Letters Patent No. 768,312, dated August 23, 1904.

Application filed. ce 5, 1903. Serial No. 183.992. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD T. ROBINSON, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Sliding-Door Gruides, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a guide for directing'the travel of doors, the guide being more particularly applicable to the doors of streetcars, the object of the invention being to furnish a guide of a construction that will accu rately direct the path of travel of the doors and one in connection with which no projections are necessary in connection with the threshold or tread plate beneath the door.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a top view of a pair of my guides and the tread-plate beneath them, frag ments of the doors by which the guides are carried being illustrated in section. Fig. II is aside elevation of the parts seen in Fig. I. Fig. III is a vertical section taken on line III III, Fig. II. Fig. IV is an elevation of one of the door-guides, with the parts beneath it Shown in section, taken on line IV IV, Fig. II.

1 designates the tread-plate of a street-car doorway, which, as seen in Figs. III and IV, is preferably formed with a vertical outer face 2 and a beveled inner face 3. This tread-plate is preferably of metal.

A and B are mating sliding doors which are suspended in any usual manner above the tread-plate 1. One of these doors is grooved vertically at its edge, and the other door, B, has

a tongue O, that is adapted to enter the groove in the first-named door.

4 designates the main body of the guide, that is carried by the grooved door A and which is of .U shape, having rearwardly-extending arms 5. In the face of the body Lat the edge of the door A is a groove 6, corresponding to the vertical groove in said door.

7 is an outturned wing extending horizontally from the outer body-arm 5 and then downwardly in the form of a lip 8,-which extends in a line parallel with the vertical face of the tread-plate 1.

9 is a wear-block, preferably of rubber, fitted to the inside face of the lip 8 and adapted to ride in contact with the outer edge of the tread-plate 1.

10 is a brace-rib connecting the outer bodyarm 5 and the wing 7 to reinforce Said wing.

11 is an inturned wing extending horizontally from the inner arm 5 of the guide-body and carrying a downturned lip 12, which extends in a line parallel with the beveled inner edge 3 of the tread-plate 1. V

13 is a wear block fitted to the inner face of the downturned lip 12 and adapted to ride in contact with the inner edge of the tread-plate during the movement of the guide thereover. The inner body-arm 5 and the wing 11 are united by a reinforcing-rib 1 1.

A designates the body of the guide carried by the door B and having the arms 5 corresponding to the arms 5 of the guide-body 4. The guide-body 4: bears a tongue 6, that corresponds with the tongue O, carried by the door B, and which is designed to enter the groove 6 in the guide-body 4 of the opposing guide on the door A. In other respects the guide carried by the door B is similar to the I guide on the door A, which has been fully described, it having the wings 7 11" united to the body-arms by reinforcing-ribs 10 and 1 1 and the down-turned lips 8 and 12. These lips also bear wear-blocks (not Shown) similar to those 9 and 13 hereinbefore referred to.

It will be seen that my door-guide may be either right or left hand and carried by either a single door or a pair of mating doors and will readily and efficiently direct the travel of the door or doors to which they are applied and cause even and uniform movement of the doors without there being any presence of projections on the tread-plate,which are a frequent source of annoyance upon the treadplates of street-car doors.

I claimas my invention 1. In a guide for sliding doors, the combination with a tread-plate, of a body portion jeeting outwardly from two sides of said body portion and having means for engagement with said tread-plate, substantially as set forth.

2. In a guide for sliding doors, the combination with a tread-plate, of a body portion fitted to the door, having wings projecting outwardly from two sides of said body portion, provided with lips projecting downwardly from said wings to engage said tread-plate, substantially as set forth.

3. In a guide for sliding doors, the combination with a tread-plate, of a U-shaped body portion fitted to the door, having wings projecting outwardly'from said body portion, provided with lips projecting downwardly from said wings to engage said treadplate, substantially as set forth.

4. In a guide for sliding doors, the combination with a tread-plate, of a U-shaped body portion fitted to the door, haying wings projecting outwardly from said body portion, provided with lips projecting downwardly from said wings to engage said tread-plate and reinforcing-ribs uniting said body portion and wings, substantially as set forth.

5. 111 a guide for sliding doors, the eoinbination with a tread-plate, of a body portion fitted to the door, having wings projecting outwardly from said body portion, provided with lips projecting downwardly from said wings to engage said tread-plate, and wearblooks carried by said lips, substantially as set forth.
